GOAL-GAS-GENERATING APPARATUS.

To all whom it may concern Be known that I, HENRY A. CARPENTER, a citizen of the United States, and a resident of Sewickley, in the county of Allegheny and Stateof Pennsylvania, have invented certain new and useful Improvements in Coal- Gas-Generating Apparatus, of which the following is a specification. I

' A serious difficulty in the operation of coal gas generating apparatus is the tendency of solids carried forward by the gas or which form therein by condensation to deposit on the walls of the offtake passages and so clog and obstruct the same as to greatly retard the operation unless thepassages are frequently cleaned. In apparatus of prior design the gas is conducted from the retort to the stand-pipe through a connecting connicating port is formed.

duit or passageway of appreciable length which affords ready lodgment for the obstructing solids, v

The primary object of this invention is to so construct and assemble the retorts or their mouth-pieces and the stand-pipe as to eliminate a connecting conduit of appreciable length by arranging said parts in abutting relation. of the communicating opening is still further reduced by eliminating one of the abutting walls, so that the abutting portions of the closely adjacent parts are separated only by a single wall through which the commu- In the present adaptation v the adjacent side of the retort mouth-piece is open and is adapted to fit against and be closed by an upright wall of the stand-pipe, the latter being provided with the port through which communication is maintained. Thus, while an efficient gas latter and providingthe direct 'portedoutlet therefor without'the intervention of connecting conduits.

A. further purpose is to provide valve means of improved construction for controlling communication between the retorts and stand-pipe.

The axial length or extentv is a sectional plan of a portion of .a gas Specification of Letters Patent. Patent-( 3d May 255, 1915. V Application filed September 14,1914. Serial No. 861,493. I

bench equipped with the invention, the re;

tort at the left hand of the view being shown n top plan, and the retort at the right hand 1n sectional plan, the adjacent portionsv of the right hand retort and the stand-pipebg ing shown on the irregular line 1- -1 of Fig;

3. Fig. 2 is a view partly in front elevation and partly in section of retorts and a portion of the length of a stand-pipe constructed in accordance with the invention. Fig; 3 is a vertical longitudinal section of apoi -i tion of a stand-pipe taken on the line 33 of Fig. 1.

Referring to the drawings, the retorts 2 are set in a bench in the usual manner, and constituting an extension or continuation of each retort is a mouth-piece 3, the open outer end of which is closed by door 4 in the usual manner. 'The opposite side Walls of the mouth-piece are equally spaced from .the longitudinal center of the mouth-piece, there being no lateral neck-like offset for connecting with the stand-pipe such as has been usually provided heretofore.

In order to eliminate the conduit or pas sageway of appreciable length heretofore in-- terposed between the retortor mouth-piece and the stand pipe 5, an upright wall of the latter is caused to abut one side of the mouth-piece. To minimize as faras possible the thickness of material between the mouth-piece and stand-pipe, an abutting wall of one of the parts is eliminated so "that they are separated only by the thickness of" the wall of the other part. In the present adaptation this is accomplished by forming the abutting face of the mouth-p1ece open with the stand-pipe fitting and clos ng the same. A structurally desirable arrangement is to form the outer end of the mouth-piece with flange 6 and its inner end with flange 7, with the space between the flanges of just sufficient width to receive the stand-pipe and. with the flanges secured to the latter, thereby firmly uniting the parts. Also, .the-.,to]i

and bottom of the mouth-piece 'mayqaber' as shown. When two rows or tiers of retort-s are connected to the same stand-pipe,.the1

, retort through a port 9 formed in the standpipe wall.

When communication between the retort and stand-pipe is valve controlled, the valve 10 for each port- 9 isof disk form and slidable onthe inner surface of the stand-pipe, said surface providing an eflicient seat, and the sliding of the valve and its pressure agalnst the seat maintains a gas-tight -fit. Pressure of the valve toward its seat is afforded by the valve-carrying spring arm 11 which is secured to the inner end of shaft 12, the latter extending through the wall of the stand-pipe beneath the retort and parallel with the axis of port 9. The shaft is rotatable in the housing 13 secured to the stand-pipe, with a spring 14: confined in the housing behind the handle-carrying head 15 of the shaft for exerting pressure in a direction to hold valve 10 tightly on it's seat. and spring arm 11 cooperate inmaintaining the seat-cleaning and gas-sealing functions of the valve. The angular bracket-like portion 16 of housing 13 serves to closeslot or passage 17 in a corner of the stand-pipe through which valve 10 and its supporting and operating arm 11 are entered and re: moved without detaching them from the housing. Hence, to repair or replace the valve it is only necessary to remove the housing-securing bolts 18 and so turnor cant the housing as to pass the arm and valve through the slot.

I claim 1. In gas generating apparatus, a horizontal retort, and a stand-pipe at one side of the'retort and extending above and below the same with a vertical wall of the pipe abutting against one side of the retort 1 and in ported communication therewith.

above the other, and a stand-pipe at one side of and extending above and below the retorts and in abutting reiation therewith,

the abutting portions of the stand-pipe andretorts being ported to place each retort in direct communication with the stand-pipe. 4;. In gas generating apparatus, a hOI'lzontal retort and retort mouth-piece, and :1

Thus it'will be seen that spring 14 stand-pipe at one side, of the mouth-piece with a vertical wall of the pipe. abutting against one side of the mouth-piece and in ported communication therewith, the mouthpiece flanged to overla the stand-pipe with flanges projecting from the pipe-abutting.

side of the mouth-piece with the flanges overlapping and secured respectively to the front and rear walls of the stand-pipe.

6. In gas generating apparatus, a retort- I mouth-plece and a stand-pipe arranged slde by side with a wall common to and separating the adjacent sides of the mouth-piece and stand-pipe, said wall having a port for establishing communication between the mouth-pieeeand stand-pipe, and a valve for said port.

7. In gas generating apparatus, a retort and a stand-pipe arranged in abutting relation with the wall of the abutting portion of one of said parts removed and with the abutting wall of the Other part separating said parts, said wall provided with a port through which the parts communicate.

8. In gas generating apparatus, a standpipe, and a retort mouth-piece having an open side with said open side fitting and closed by .a vertical wall of the stand-pipe,

. the stand-pipe wallformedwith a port for establishing communication with the mouthpiece.

9. In gas-"generating apparatus, a retort vmouth-piece having a wall forming a continuation of a corresponding retort wall and.

with the said mouth-piece wall open, and a stand-pipe at one side of the mouth-piece with a vertical wall of the stand pipe fitting and closing the open mouth-piece wall,-the

stand-pipe wall having a port for establishing communication with the mouth-piece.

10. In gas generating apparatus, a retort mouth-piece having an open side with lateral extensions on the mouth-piece adjacent to the opening, anda stand-pipe fitting between and secured to said extensions with a vertical wall of the pipe closing the open side of the mouth-piece, the stand-pipe wall having a port for establishing communication with the mouth-piece.
